s WARP-DRAWING MACHINE.

, all whom it may concern:

Be it known that I, Minn-tin) F. FIELD, of Boston, in the county ofSuffolk and State of Massachusetts, have invented certain new andusefulImprovements in Tarp-Drawing hflachines, of which the following is adescription sufficiently fulh'clear, and exact to enable those skilledin the art to which it appertains or with which it is most nearlyconnected to makeand use the same.

a This invention relates to warp-drawing ,for the purpose mentioned; butthe said machines or devices Constructed more particularly for thepurpose of controlling thememhers of a series of independent detachedheddles, or other threacl-engaging loom elements, and also the mechanismfor drawing warp threads intoythe eyesor openings of such detached loomelements, although in many respects the invention is applicable topurposes other than those referred to and other than the particularoneswith reference to which the invention is-herein lllllStlfflteChI'have heretofore invented and had patented by me, under Patent No.600,070, dated March 15, 1898, a machine of the kind and machine was notshown tobe so organized as to best adapt it to operate upon metalhcherein considered, of thin strips of steel or other Slfllllllflnzltellfil arranged upon or suspended from a'horizontal bar in planesparallel withthe lineof extension of the warps,: the/eyes for; thereception of the tinned 'heddles, and hence the impossibility,

able to see,-of making oneadvantage for 1 i so far as Iain new mach neto, answerto 1 good both purposese that; 1s to say, fQI' RCiJlOIlwarp-threads being formed transversely through the heddles, or on a lineat right angles to the line of extensionof the warps. Metallic heddlesof this kind, by reason of their peculiar construction and arrangement,as compared with heddles formed from fibrous cords, are not so readilycontrolled by mechanical means as arejthehast-men upon both kinds ofheddles.

It is the purpose in the present invention to so organize and perfect amachine "that it will be capable of selecting, separating, disengagmgorreleasing s1ngly, success1vely,

andqwithcertainty, the detached or independent metallic 'heddles in thedesired 0rder,'dra\ ving eachmheddle aside as it is Specification ofLetters Patent.

The magnet and its support, in this case,forms a selector or separator.

Itwill now be seen that when the slide plate 0 is reciprocated, as itmay be by an eccentric or cam e on the cam shaft operating a rod 0 so asto move the said I'od lengthwise, and through suitable connections, asshown in Fig. :2, operating in like manner a rod 7 connected to theslide plate, the magnet will be moved up, say, first against the outerone of the series of heddles s, then moved back, drawing with the heddlewith which'it was brought into contact, the friction between the heddlesand their supporting bar serving to hold back the other heddles, thenwill be moved over to the line of heddles s and up against the heddle inthat sedraw it back, and will thus separating the first ries from theothers and the same operation In Figs. 10 to 13, inclusive, it is shownhow the lower end of thezbar b is operated upon to cause it to performthe successive steps herein just described.

Instead of employing a magnet on the bar 6 as described, I may use amechanical device such as is shown in.Figs. 8 and 9, and which consistsof a selector or separator g having inclined resilient sides adapted onthe opposite sides of the heddle, and wedge the latter between the saidresilient sides sufiiciently firm to enable it to be held and drawn awayfrom the others, as hereinbefore described with respect to the magnet.In this case it is only necessary that the inclined sides should bemaintained in place resiliently, it being an derstood that this may beaccomplished in I have shown the last mentionedform of heddle selectoras being made double so that'one can act upon one line of heddles andthe other upon another, but this is an expedient not necessary ofadoption, since one resilient pair of jaws 9 may pairs to'engage theheddles by their edges,

and select and separate themsingly as the lips of the screws it comeinto contact-with In Fig. 19 of the Said drawings, the arrows I berepeated throughout the two series of heddles.

itsopposite end a pinion 1", engaged by a around the. screw-shafts 72,indicate the direction of revolution of the screws. This form ofselector or separator has been found eflicient and desirable for mostcases.

When bymeans of the devices and mechanism just described, a heddle hasbeen selected and separated from the mass hanging in a harnessand placedin proper position, it is taken hold of and operated upon by themechanism which I have designated a gripper which is illustrated in itsrelative position ,in the machine in Figs. 2, l and 5, and in detail inFigs. 6, l-t, 15', 10, 16

This gripping mechanism consists of a shaft 122. stepped in the frame ofthe maq chine, as seen in Fig. 6. around .which shaft is a. sleeve Z,provided with a miter gear 0 by which the sleeve is turned. Near the topof the shaft m. there is secured a pair of arms j, 9' which projectradially therefrom at about a right angle with one another, and each ofwhich constitutes one jaw of the gripper. Another pair of arms 1?, iwhich constitute the other jaws of thg gripper, are secured to thesleeve l anc project substantially diametrically there ,from, and in thesame horizontal plane with the arms 3", 9' which latter project througha circumferential slot '11- of about 180, in the sleeve Z, Fig. 4. Thesleeve Z is given a reciprocating rotary movement around the shaft on,by means of its gear 0, which meshes with a corresponding gear p uponthe end of a shaft (1, Fig. 5, which has upon toothed segment t, whichis caused to osvcillate by its connection through a pitman with a crankr, secured to a small gear M which meshes with a large gear-.2" upon theshaft 2, (see Fig. 1). There is also secured upon the shaft 2"a ratchetwhee] a which is engaged by a pawl rod I). pivoted to a lever 71, whichlever is thrust forward by the double camon the shaft (1: therebyturning the ratchet (1, gear .1 and all connected mechanism,intermittently as the cam rotates. A spring 71" holds the lever I)constantly in contact with said -am I). By means of an intermediateidler gear 11. which meshes with the gear m and a pinion k on the end ofthe shaft 9' that shaft and the warp-separating screw upon its oppositeend are' also intermittently turned by the operation of the ratchet (l-From the same source also an oscillating motion is given to a pair'ofheddle holding fingers gtupon a shaft f through. its connection with thesegment 15', by means of a short arm 0 pitman d, and crank 0 The'fingers g have av beveled face so that/as they swing back and forththey will crowd between the heddle last selected and the next succeedingone and holdit back with the mass of heddles beyond, while the sleeve 7from the )osition shown in Fi 14 to that shown in Fig. 15, thereby grip-I ping the heddle s between the two jaws z, j. As the sleeve Z continuesto revolve it carries the two jaws of the. gripper with the heddlebetween them around to the position shown in Fig. 16; thereby twistingthe lower end of the thin metallic heddle about, so as to present itsflat side toward the needle point and place its eye in proper positionfor the passage of the needle in drawing in a warp-thread. As soon as.the needle has drawn a warp-thread into the -=.e ve of the heddle a. theaction of the crank "r and the segment gear 1" turns the sleeve l in theopposite direction and the arm 5- i is thereby caused to catchthe.heddle s which has been separated from the mass in the second harness.and press it against the arm j". and as the sleeve Z continues torevolve the heddle s is twisted about and carried to the position shownat 3, Fig. 1-1, ready for the passage of the needle through its eye; andthus the operations are repeated alternately upon each heddle containedin the two harnesses.

In Fig. 19, the heddle gripper is shown in its proper positioninrelation to ,the screw heddle-separating devices It, hereinbeforedescribed.

WVhen each heddle is released by a gripper in its reverse action, theheddle may be pushed forward out of the av of the gripper jaws by apush-rod 7a, which is operated by a cam on the shaft d'shown in sideelevation in Figs. 1 and 2,'and in plan in Fig. 7.

A single'pair of grippers only may be employed to turn and presentthe'heddles to the needle, but in order to hold the heddles more securelytwo pairs of grippers may be used to grip the heddle above and below theeye as illustrated in Figs}; and (3.

In Fig.'16.I have shownthe heddle selector mseparator and gripper andturner, combined in onedevice. The arms or gripper-jaws j, 7' are mademagnets, and as shaft is operated first, forexample, so as to carry themagnet arm j back into contact preferably I caused to swing down andgrip the separated heddle s between itself and the jaw j.

- This latter operation is accomplished by means of a pin i -whichprojects from the endqot an arm 1 into a suitably formed slot 2 H1the'rear portion of the arm 2'.

The arm it is secured to the shaft 7%, and" as that shaft rotatesitcauses the pin i to slide along in the slot 2' thereby causing the arma" 'to turn upon its pivot in the stationary support, and swing downagainst the arm j, and as in the operation of the construction shown 1nFlg. 16, the continued rotation of the shaft m with the gripper .ipj,will twist the lower end of the bed dle into the position shown inv saidFig; 16,

ready for the passage of the drawing-in needle through its eye.

As will he observed by an inspection of Fig. 16 a pair of separating andgripping devices ofthis modified construction is provided upon 'theshaftm", the second one consisting of arms 1?, j and connected partssimilar to those connected with arms 2', j, so that thegrippers mayoperate alternately upon the heddles of two harnesses. The warps passfrom the warp-beam upward against the shaft y and separating screw 70and their ends are laid .lpon the tension roller :12, or betweenclamp-bars.

The tension device :1: shown in Figs. .1, '2 and 3 consists of a rollcovered with card clothing into which the ends of the'warpthreads arelaid and by which they are held; and the tension is secured by turningthe said roll in by means of the hand-wheel i (rig, ,3)in..,the"direetion indicated by the arrow in said figures, thus drawingthe warp-threads taut and holding them in that condition by aWeighted-strap passed over a pulley (not shown) on the shaft of thetension roll andoperating with a tendency toturn itso as to keep thethreads stretched. Instead ofemploying the tension roll :1: I 1nay, andin many cases prefer to, use clamping-bars as heretofore stated.

Itwill be noted that only that portion of the heddle containing thewarp-eye '1; need be turned by the grippers; andthalain acting upon thatportion, the part below the eye will, also be turned, which will resultin freeing the lower end of the heddle which being acted upon from theheddleguiding meansa nd their stop, so that the h'eddle after beingthreaded may be pushed In substantially all cases I find it neces-' saryto assemble the heddles, from their normal positions, into asubstantially compact mass before acting upon them to separate themsingly and successively and to turn the eye portion so that the needlemay pass through the he'ddleeye and catch a warp-thread and draw it in.Any arrangement of the heddles, however, that will (an-- able them to beproperly operated upon will subserve' the purposes of theinvention. Itwill be seen that the warp-thread spacing-screw and its shaft areintermittingly rotated; the sudden starting and stopping tending bettertoward 'straighteping out the warp-threads, should they be crossed orotherwise entangled, than as though the rotation of the said screwandits shaft/were continuous andregulara It is to be understood that mvinvention not only contemplates the drawing of warp threads through theeyes of the beddies of a metal harness and the control of i suchheddles, but alsothe drawing of. threads through and thecontrol of-otherlike devices such, tor example, as metallic, drop bars, sometimes calleddrop heddles, for stop motions which are employed in connection with thewarp of a loom.
